Backplate 4,5"
Backplate 4,5" is a Folding propeller backplate from Mejzlik Propellers, prepared for RC-MODEL customers with practical fitment guidance, structured specifications, product imagery and no supplier pricing.
Recommended use
Use this item for folding propeller hub/backplate setup. Confirm diameter, pitch, rotation, blade count, hub/backplate fitment, engine or motor load, RPM range and airframe clearance before ordering.
What to confirm before ordering
Carbon propeller selection should consider the complete propulsion setup: motor or engine power, battery voltage or displacement, expected RPM, thrust requirement, mounting pattern, balancing and safety margin. RC-MODEL can help verify the correct part when you provide the aircraft/UAV setup and part number.
